Fixed-Point Arithmetic in FPGA

Arithmetic operations are among the most frequently-used operations in contemporary digital integrated circuits. Various structures have been designed, utilizing different features of IC architectures. Nevertheless, there are very few studies that consider the design of arithmetic operations in Field Programmable Gate Arrays (FPGAs), a re-programmable type of digital integrated circuit. This text compares the results achieved when implementation of basic fixed-point arithmetic units in FPGA.
